Referring to FIG. 1, Fig. 1 is the schematic diagram of the application one embodiment display panel；The application provides a kind of display surface Plate is disposed in proximity to described including viewing area AA and around the non-display area NA of viewing area, driving chip IC, driving chip IC The first side of the non-display area NA of the first side viewing area AA, viewing area AA and second side of viewing area are oppositely arranged；It is with Fig. 1 Example, downside are the first side of viewing area AA, and the upside opposite with downside is second side of viewing area AA.Display panel further includes engraving Dead zone TH, vacancy section TH are set to viewing area AA；Vacancy section TH includes close to the first edge of driving chip IC and far from driving The second edge of chip IC；By taking Fig. 1 as an example, the downside of vacancy section TH is first edge, and the upside of vacancy section TH is second edge. In order to promote the screen accounting of display panel, the other elements of display device are prevented in display panel setting vacancy section TH, such as take the photograph As head, earpiece, light sensor etc..It should be noted that the vacancy section TH of the application can be the non-display area after cutting, It can be uncut light transmission non-display area.

After vacancy section TH is arranged in display panel, display panel is divided into three regions by the application, referring to FIG. 1, this The display panel of application includes the first viewing area AA1, and the first viewing area AA1 is extended to described by the first side of the viewing area AA Second side；Second viewing area AA2, the second viewing area AA2 extend to the viewing area AA's by the second edge of vacancy section TH Second side；Third viewing area AA3, the third viewing area AA3 extend to the vacancy section TH's by the first side of the viewing area First edge；First viewing area AA1 is provided with the first data line 11；Second viewing area AA2 is provided with the second data line 12； Third viewing area AA3 is provided with third data line 13；Wherein the first data line 11, the second data line 12 and third data line 13 Contribute to transmission data-signal.Since data-signal is provided by driving chip IC, under normal circumstances, the number of data line such as first Second side is extended to by the first side of viewing area AA according to line 11.But due to the presence of vacancy section TH, lead to third viewing area AA3 Third data line 13 can not extend to corresponding second viewing area AA2, if will to the second viewing area AA2 provide data Signal, then data line has to that this edge frame increasing that will lead to vacancy section TH is arranged along the edge coiling of vacancy section TH Add, reduces screen accounting, influence visual effect.And in the application, first data line 11 of at least partly the first viewing area AA1 It is correspondingly connected between second data line 12 by switch unit 30.Specifically, switch unit 30 can passing through with timesharing Second data line 12 is transferred to third data line 13；When switch unit 30 be connected when, driving chip IC by with the second data line First data line 11 of 12 connections transmits data-signal to the second viewing area AA2, when switch unit 30 ends, driving chip IC Data-signal is only transmitted to the first viewing area by the first data line 11.At this point, being transferred to first since switch unit 30 ends The data-signal of viewing area AA1 does not interfere with the second viewing area AA2.

Specifically, referring to FIG. 3, Fig. 3 is the schematic diagram of the switch unit of the application one embodiment；In the present embodiment, Switch unit 30 includes at least one switching transistor 301, and the first pole of each switching transistor 301 connects first data line 11, the second pole connects second data line 12, and the grid of each switching transistor connects same control signal wire 3011.This implementation Example, when control signal wire 3011 provides low level control signal, respectively switchs crystal so that switching transistor is P-type transistor as an example Pipe 301 opens simultaneously, and driving chip IC is by the first data line 11 for connecting with the second data line 12 to the second viewing area AA2's Second data line 12 provides data-signal；When control signal wire 3011 provides high-level control signal, each switching transistor 301 End simultaneously, driving chip IC is by providing data-signal to the first viewing area AA1 with the first data line 11.The application is cleverly By switch unit 30, the first data line 11 is being reused respectively to the first viewing area AA1 and the second viewing area AA2 transmission letter Number while, avoid the signal interference between two viewing areas.And the application avoids data line coiling, reduces hollow out The border width of area TH.

In another embodiment of the application, it is understood that there may be the pixel columns of the second viewing area is greater than the first viewing area Pixel columns, the number of the second data line 12 of the second viewing area AA2 is greater than the first data line 11 of the first viewing area AA1 at this time Number.At this point, can have some second data lines 12 if according to previous embodiment without corresponding first data line 11 can be attached thereto.Therefore, referring to FIG. 4, specific Fig. 4 is the signal of the switch unit of another embodiment of the application Figure；

In the present embodiment, switch unit 30 includes at least one set of multi-channel switch module 31, and one group of multi-channel switch module 31 wraps Include n transistor；One the first data line 11 connects with the second data line of n item 12 by the way that multi-channel switch module 31 described in one group is corresponding It connects；Multi-channel switch module 31 includes n transistor and n control signal wire；The first end of each transistor and same first data Line 11 connects；The second end of each transistor is connect with each second data line 12 respectively；The control terminal of each transistor respectively with each control Signal wire connection processed；N is the integer more than or equal to 2.Fig. 4 illustrates the multi-channel switch module 31 of the application by taking n=2 as an example.This One group of multi-channel switch module 31 of application includes a second transistor 302 and a third transistor 303；Second transistor 302 connect the first signal wire of same 11, second transistor 302 and third transistor 303 with the first end of third transistor 303 Second end respectively connect two the second different data lines 12, the control of second transistor 302 and third transistor 303 End respectively connects two different control signal wires, second control signal line 3021 and third control signal wire 3031.This In still by taking 303 P-type transistors of second transistor 302 and third transistor as an example, when second control signal line 3021 provide Low level signal, when third control signal wire 3031 provides high level signal；Second transistor 302 is connected, third transistor 303 Cut-off, driving chip IC provide data letter to the second data line 12 connecting by second transistor 302 with the first data line 11 Number；Similarly, when second control signal line 3021 provides high level signal, third control signal wire 3031 provides low level signal When；Third transistor 303 is connected, and second transistor 302 ends, and driving chip IC is counted to by third transistor 303 and first Data-signal is provided according to the second data line 12 that line 11 connects；When second control signal line 3021 provides high level signal, third When control signal wire 3031 provides high level signal；Second transistor 302 ends, and third transistor 303 is ended, driving chip IC Data-signal is provided to the first viewing area AA1 to by the first data line 11, and due to second transistor 302 and third transistor 303 cut-offs, this data-signal will not influence the normal display of the second viewing area AA2.It is single that the present embodiment cleverly passes through switch Member 30, while the first data line 11 of recycling transmits signal to the first viewing area AA1 and the second viewing area AA2 respectively, Avoid the signal interference between two viewing areas.And the application avoids data line coiling, reduces the side of vacancy section TH Width of frame.On the other hand, the application can make 11 timesharing of the first data line by switch unit 30 to the second data Line transmits data-signal, so that the present embodiment is wider for the scope of application of relief area size.For example, when vacancy section is larger, the When the quantity of the second data line 12 of two viewing area AA2 is 1~2 times of 11 quantity of the first data line of the first viewing area AA1, enable N=2 then can satisfy the use demand of switch unit.Similarly, when vacancy section is larger, the second data line of the second viewing area AA2 When 12 quantity is 2~3 times of 11 quantity of the first data line of the first viewing area AA1, n=3 is enabled then to can satisfy switch unit Use demand.

Further, due to the sub-pixel of different colours, its data-signal for corresponding to light emission luminance is not identical, if to same The data-signal of the write-in different colours of data line will cause the problem of Data writing time deficiency, and then cause signal inaccurate Really, it is abnormal to there is display.When the first data line 11 is different with the corresponding pixel color of the second data line 12 for connection of being corresponding to it When, such as the first data line 11 is corresponding red and blue, the corresponding green of the second data line, due to green data signal range and It is red to differ bigger with blue；Such as the data wire size range of green is in 3~5v, red and blue range in 2~3v, that The second viewing area AA2 last line (last line in timing) input data signal for example from lastrow (in timing Row second from the bottom) 2v become the 2.5v of last line.For the first row (the first row in timing) of the first viewing area AA1 Write-in data-signal is the 4v for just needing corresponding green, since the pressure difference of 2.5v to 4v here is significantly larger than the former 2v to 2.5v's Pressure difference, may result in data-signal write-in is time deficiency, causes the display of the first viewing area abnormal.Therefore, the present embodiment A kind of display panel is provided, it can be to avoid the above problem.

With continued reference to FIG. 3, the first data line 11 includes the first first data line 11a being arranged alternately along first direction and One second data line 11b, the first first data line 11a connect the pixel of different colours with the first second data line 11b；First direction and institute The extending direction for stating the first data line 11 intersects；Second data line 12 includes the second first number being arranged alternately along the first direction The pixel of different colours is connect with the second second data line 12b according to line 12a and the second second data line 12b, the second first data line 12a； Second first data line 12a and the first first data line 11a is correspondingly connected with by switching transistor 301, the second second data line 12b and the One second data line 11b is correspondingly connected with by switching transistor 301.Second first data line 12a connect phase with the first first data line 11a With the pixel of color；Second second data line 12b connect the pixel of same color with the first second data line 11b.In this way, for passing through For second data line 12 interconnected of switch unit 30 and the first data line 11, to the last line of the second viewing area AA2 Be to the color of the first row of the first viewing area AA1 write-in signal it is identical, avoid color difference from causing the charging time insufficient, Cause display abnormal.It should be noted that the second first data line 12a and the first first data line 11a connection described here is identical The pixel of color not necessarily the second first data line 12a and the first first data line 11a can only connect a kind of pixel of color, It can be the second first data line 12a and the first first data line 11a while all connecting the pixel of two kinds of same colors.Such as: second First data line 12a connection is red and blue pixel, the first first data line 11a also connect red and blue pixel.

Fig. 4, Fig. 8 and Figure 10 are further combined, the switch unit 30 in the present embodiment is also possible to as shown in Figure 4 more Way switch unit.

Switch unit 30 includes multiple groups multi-channel switch module 31, and one group of multi-channel switch module 31 includes n transistor；One First the second data line of data line 11 and n item 12 is correspondingly connected with by multi-channel switch module 31 described in one group；Multi-channel switch module 31 include n transistor and n control signal wire；The first end of transistor is connect with same first data line 11；Transistor Second end is connect with each second data line 12；The control terminal of transistor is connect with each control signal wire；N is whole more than or equal to 2 Number.Previous embodiment specifically is please referred to, this will not be repeated here.

A kind of driving method is provided in the present embodiment, in the first period T1,30 timesharing of switch unit conducting, an institute It states 11 timesharing of the first data line and provides data-signal to the second data line 12.According to the method for the present embodiment, the application can make Obtain 11 timesharing of the first data line transmits data-signal to the second data line by switch unit 30, so that the present embodiment pair It is wider in the scope of application of relief area size.

Specifically, please referring to the timing of Figure 10, in the first period T1, second control signal line 3021 and third control signal The alternately transmission useful signal pulse of line 3031, so that 11 timesharing of the first data line is transmitted to two the second data lines 12 Data-signal.It should be noted that the control terminal signal wire 801 of insulation control transistor 80 is in the first period in this embodiment T1 and the second period T2 lasting output high level signal, so that the first scan line 70a and the second scan line 70b insulation.

Further, the non-display area of display panel is provided with driving the first driving circuit of the second viewing area 20a；With Drive the second driving circuit 20a and 20b of first viewing area；First driving circuit 20a is multiplexed in the second driving circuit Part.First driving circuit 20a includes the first commencing signal and the first clock signal；Second driving circuit 20b includes second Commencing signal and second clock signal；In the first period T1, to the first driving circuit provide first commencing signal and First clock signal, the first driving circuit are driven line by line；In the second period T2, to described in the offer of the second driving circuit Second commencing signal and the second clock signal, second driving circuit are driven line by line；Driving can be reduced in this way The total quantity of circuit reduces the area that driving circuit accounts for rim area, reduces border width.

Further, the width of the significant level of the first commencing signal is greater than the width of the significant level of the second commencing signal Degree；The period of first clock signal is equal to twice of second clock signal period.

Specifically, data-signal is written when scan line 70 provides significant level.However, the one of the second viewing area AA2 Significant level that scan line provides it is required that at least two data-signal timesharing write-in, therefore, the second viewing area AA2 institute The significant level width of the scanning signal needed is at least twice of other viewing areas.If entire viewing area all uses in this way Sweep time of significant level width then entire display panel will double, this can reduce the frame number of display panel.With 1920*1080 resolution ratio, for the display panel of 60 frames: the time of each frame is 16.7ms, and the sweep time of every a line is (effectively The width of level) it is less than or equal to 8.7 μ s of 16.7ms/1920 ≈.On the one hand, since the second viewing area AA2 is in the scanning of a line Between need timesharing data-signals are written to two the second data lines 12.On the other hand, needs one are sufficiently written in data-signal Shortest time, e.g. 5 μ s.So the sweep time of every a line of the second viewing area AA2 is then had to be larger than equal to 10 μ s. Total frame per second of display panel is 1s/ (10 μ s*1920)=52 frames if every a line is scanned all in accordance with this time, hence it is evident that Lower than 60 frames, this will affect the image quality of display panel.

The application setting, the width of the significant level of the first commencing signal are greater than the width of the significant level of the second commencing signal Degree, the period of the first clock signal are equal to twice of the second clock signal period, only increase the sweep time of the second viewing area And the sweep time of the first viewing area AA1 is not increased.By taking the display panel of 1920*1080 resolution ratio as an example, if second is aobvious Showing that area AA2 has x row, then the second part AA1b of the first viewing area has 1920-x row, and wherein the sweep time of x row is 10 μ s, The sweep time of 1920-x row is 5 μ s, then the total scanning time of a frame is 10x+1920*5-5x=5* (1920+x) μ s, if aobvious Show that the sign rate of panel is greater than 60 frames, then needs 5* (1920+x) μ s≤16.7ms to find out, x≤1420.That is with 1920* For the display panel of 1080 resolution ratio, 60 frames are if desired kept, according to the driving method of the present embodiment, the second viewing area AA2 Line number only need to be less than 1420 rows.Therefore, according to the driving method of the present embodiment, the display panel of the application can be real The driving of existing high frame per second.By taking n=2 as an example, the period of the first clock signal is equal to twice of the second clock signal period the application, The period of the first clock signal is equal to three times of second clock signal period when n=3, and so on.

In another embodiment of the application, Fig. 4, Fig. 8 and Figure 11 are please referred to, Figure 11 is another embodiment of the application Time diagram；

One group of multi-channel switch module 31 of the application includes a second transistor 302 and a third transistor 303；The Two-transistor 302 connects the first signal wire of same 11, second transistor 302 and third with the first end of third transistor 303 The second end of transistor 303 respectively connects two articles of different the two the third data line 12c and the second fourth data line 12d；Second The control terminal of transistor 302 and third transistor 303 respectively connects two different control signal wires, second control signal Line 3021 and third control signal wire 3031.

Figure 11 is please referred to, second control signal line 3021 and third control signal wire 3031 alternately export significant level. S1, S2, S3 respectively indicate the scanning signal of the first row, the second row and the third line in Figure 11.When second control signal line 3021 or When third control signal wire 3031 is significant level, data signal transmission to data line；When scanning signal is significant level It waits data-signal and is written to driving transistor.By taking the first line scan signals S1 as an example, if the low level of the first scanning signal S1 Cover second control signal line 3021 and third control signal wire 3031 significant level, then be in second control signal line 3021 When significant level, the driving transistor of the two the third data line 12c connections is written data-signal, and with third control signal wire 3031 Corresponding second fourth data line 12d is not written into data-signal, and therefore, data letter is not written yet for driving transistor connected to it Number；When third control signal wire 3031 is significant level, the parasitic capacitance as present on the two the third data line 12c, second Data-signal is persistently written in the driving transistor of third data line 12c connection, and data letter is written in the second fourth data line 12d at this time Number；Therefore, it can be seen that the time of the driving transistor write-in signal of the two the third data line 12c connections is than the second fourth data line The time of the driving transistor write-in signal of 12d connection is long, it may appear that display is abnormal.But work as the effective of the first scanning signal S1 When level is located at after the significant level of second control signal line 3021 and third control signal wire 3031, the two the third data lines Signal is written than the driving transistor of the second fourth data line 12d connection in the time of the driving transistor write-in signal of 12c connection Time is identical, but second control signal line 3021, third control signal wire are located at interval between two scan periods at this time The significant level of 3031 significant level and the first scanning signal S1.Setting interval time can reduce display panel more long in this way Frame per second.

In one embodiment of the application, the significant level of setting third control signal wire 3031 is located at the second control letter After the significant level of number 3021 sum of line, and the significant level of second control signal line 3021 and the significant level of scan line are not handed over It is folded, the significant level of the significant level covering third control signal wire 3031 of scan line.At this point, second control signal line 3021 is When significant level, the two the third data line 12c are written data-signal, but the non-write driver transistor of signal, the second fourth data line 12d is not written into data-signal；When third control signal wire 3031 is significant level, due to being deposited on the two the third data line 12c Parasitic capacitance, the driving transistor of the two the third data line 12c connections is held into data-signal, and the second fourth data line at this time Data-signal is also written in 12d；Therefore, the two the third data line 12c and the transistor of the second fourth data line 12d connection write-in data letter Number time it is identical, it is abnormal to avoid the occurrence of display.

On the other hand, in the present embodiment, when being not necessarily to carry out time sharing transmissions data-signal within the scanning period, but being divided to two Section is scanned, and transmits data-signal respectively, then different scanning letters is arranged in the time of the every grade of scanning identical region that do not need to distinguish Number limited level width, greatly reduce the complexity of IC.
